1972 — Jacob Bekenstein suggests that black holes have an entropy proportional to their surface area due to information loss effects; 1974 — Stephen Hawking applies quantum field theory to black hole spacetimes and shows that black holes will radiate particles with a black-body spectrum which can cause black hole evaporation
History of black holes. Timeline of black hole physics – Timeline of black hole physics; John Michell – geologist who first proposed the idea "dark stars" in 1783 [3] Dark star; Pierre-Simon Laplace – early mathematical theorist (1796) of the idea of black holes [4] [5] Albert Einstein – in 1915, arrived at the theory of general relativity
Supermassive black holes, regions of space where the pull of gravity is so intense that even light doesn't have enough energy to escape, are often considered terrors of the known universe.
This paper predicted the existence of what are today known as black holes. [1] [7] The term "black hole" was coined decades later, in the fall of 1967, by John Archibald Wheeler at a conference held by the Goddard Institute for Space Studies in New York City; [7] it appeared for the first time in print the following year.

In 1974, Hawking predicted that black holes might not be the bottomless pits we imagine them to be -- and now, there may be evidence to support that theory.
India’s new mission, expected to last for about 5 years, could help understand the X-ray emission mechanism of various astronomical sources like black holes, neutron stars, and star forming nebulae.
2019 – Advanced LIGO and VIRGO detect GW190814, the collision of a 26-solar-mass black hole and a 2.6-solar-mass object, either an extremely heavy neutron star or a very light black hole. [292] [293] This is the largest mass gap seen in a gravitational-wave source to-date.
2019 – The Event Horizon Telescope Collaboration publishes the image of the black hole at the center of the M87 Galaxy. [114] This is the first time astronomers have ever captured an image of a black hole, which once again proves the existence of black holes and thus helps verify Einstein's general theory of relativity.
